Hailey Bieber, Bella Hadid and Stassie Karanikolaou are very close friends … and, what’s more friendly than puckering up and smooching one another on girls night???

Anastasia, AKA Stassie, shared a video alongside her two pals … Bella in the middle of Hailey and Stassie when they all lean in to pose for a selfie clip.

Bella grabs her gal pals’ faces and brings them in closer … and, the three pucker their lips — with Hailey and Stassie ultimately kissing Bella’s cheeks.

No lip-to-lip contact here … just some chaste kisses among buds — talk about a bonding experience!

This all went down at Stella — a popular celeb hot spot in L.A. — where Bella was celebrating her collaboration with Frankie’s Bikinis … sipping on signature cocktails and posing alongside her model friends.

While Bella got to enjoy her business success in the evening, the afternoon belonged to Hailey … ’cause fans flocked to her store Rhode for a pop-up event that created a line all the way out the door.

Check out the clip … people are queued up all the way down the block, and the line even snakes around the parking lot as everyone waits to buy the newest product from the brand.
